Abstract: A sensor connecting unit includes a safety input for connecting with a sensor; a power supply that is controllable through a controllable power switch; and a first I/O processing unit and a second I/O processing unit being connected to each other through a reciprocal comparison communication channel. The first I/O processing unit and the second I/O processing unit are both connected through a measurement circuit to measure voltage, current or power between a reference input and the safety input, and connected to a safety bus. The first I/O processing unit informs the second I/O processing unit about switching off of the controllable power supply, the second I/O processing unit commands the first I/O processing unit to switch off the controllable power supply, and/or the second I/O processing unit measures an output of the controllable power switch to detect switching of the power switch.

Abstract: Conventionally, elevator communications have been implemented using travelling cables. This is particularly the case when safety related data transmitted from an elevator car has to fulfil real-time restrictions often set by regulators so that the receiving of the information may not be delayed. Typically, this cannot be guaranteed when wireless transmission technologies are used. The reliability can be increased by using a second to supplement the wireless transmission.

Abstract: Elevator safety and safety related information needs to be sent reliably to safety controlling systems. Existing elevator communication devices may be used for transmitting this information by processing the received safety and safety related information and processing it before sending it over the communication bus from the elevator car or floor equipment to the controlling devices. A separate communication unit may be used for receiving and processing safety and safety related data packets before they are transmitted over a common bus used for safety and safety non-critical submission.

Abstract: The invention refers to a method for accessing an passenger transportation device control means comprising several separated printed circuit boards (PCB), whereby each of these PCBs comprises a unique identifier (ID), and in which method the passenger transportation device control means comprise a matching table which is used by the passenger transportation device control means to perform a matching test to check the identifier of at least two of the PCBs and to put the passenger transportation device control means into normal operation only if their IDs match the IDs of the matching table. A service technician connects via a key to the passenger transportation device control means, which key enables the service technician to set the passenger transportation device control means into a fault finding mode, in which fault finding mode the passenger transportation device control means are initiated to skip the matching test before getting into operation, whereby the fault finding mode is terminated at the latest when the service technician terminates the key-based connection with the passenger transportation device control means.

Abstract: A method and an arrangement are provided for monitoring the safety of a counterweighted elevator. In the method, an elevator car is driven with a hoisting machine towards the top end of the elevator hoistway, contact between the counterweight and the end buffer of the elevator hoistway is determined, a reference point for the location of the elevator car is registered when detecting contact between the counterweight and the end buffer, the distance that the elevator car travels onwards from the aforementioned reference point for the location is measured, and if the distance traveled by the elevator car onwards from the aforementioned reference point exceeds a threshold value a signal indicating a risk of slackening of the traction rope is formed.

Abstract: A method and a safety arrangement are provided for monitoring the movement of an elevator component, more particularly of an elevator car or of the automatic door of an elevator. In the method, a setup drive of an elevator component is run, and the speed and/or acceleration of the elevator component is measured during the setup drive, a threshold value for the speed and/or acceleration of the elevator component is formed on the basis of the measuring data obtained in the setup drive, the speed and/or acceleration of the elevator component is measured, and if the measured speed and/or acceleration exceeds the aforementioned threshold value, a monitoring signal for bringing the elevator to a safe state is formed.
